TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 453,941, dated June 9,1891.

Application filed April 2, 1890. Serial No. 346,310. (No model.

To all whom it may concern.-

Be it known that I, WALTER M. REASON, of Oaro, in the c'ounty of Tuscolaand State of Michigan, have invented a new and useful Improvement inType-Writers, of which the following is a specification.

Myinvention relates to type-Writers; and the object of my improvementsis to adapt a typewriting machine to write either capital or smallletters with one set of keys. I attain this object in the deviceillustrated in the accompanying drawings, in Which Figure 1 is a planview of a type-writing machine embodying my invention, the papercarriageand all but one pair of the type-bars being removed. Fig. 2 is a sectionon the line 00 01:, Fig. 1. Fig. 3 is a plan view of the shifting-ring,and Fig. 4 is a perspective View of one pair of type-bars and a part ofthe operating mechanism.

Similar letters of reference refer to similar parts throughout theseveral views.

A is the frame of the machine.

13 is the opening at the periphery of which the type-bars are secured.

I is a type-bar which carries a capital letter, and i is a type-barwhich carries a small letter. Said type-bars are pivoted upon a rod to,which rod is secured to the top plate of the machine near the peripheryof the opening B. The other type-bars are secured in the same way andare similarly arranged, a bar carrying a small letter adjoining a barcarrying the corresponding capital letter.

I d e, i d f are the bell-crank levers, pivoted at b 0, upon the longarms I 2' on which the type are carried, and e f are wrists extendingfrom the free ends of the webs (Z (Z toward each other, their free endscoming together with their centers in line. The free ends of the wristse f are beveled in opposite directions, as shown in Fig. 4:.

J is a Wire connecting the wrists e f with the lever of the key whichoperates the typebars I and v I j is a loop formed in the end of thewire J, passing over and adapted to slide along the wrists e f.

a key at said lower end.

. S is a bar along which the wheel travels which supports the front ofthe paper-carriage.

T is a lug extending from the lower part of the rod S at its center tothe center of the opening B.

O is a hub pivoted on the end of the lug T concentric with the openingB. An aperture is formed through the center of the hub O to permit thetype to pass to strike the paper upon the platen.

D D D are arms extending radially from thehub O beyond the periphery ofthe opening 13. The arm D, which extends toward the front of themachine, passes through an aperture formed for that purpose through therod S.

F is a ring provided with radial slots g. Said ring is supported withits center directly below the center of the opening B by rods E E,extending vertically downward from the ends of the arms D D throughslots R, formed through the top plate of the machine. The wire J passesthrough one of the slots g, and is adapted to move freely in thedirection of its length in said slot.

II is a lever pivoted at the lower end of the hanger G and extending atits lower end to one side of the key-board, and provided with The upperend of the lever H engages with a slot in the periphery of the ring F,as shown in Fig. 3.

w is a spring secured to the hanger G and acting to press the upper endof the lever I-I backward.

P P are radial slots formed in the ring F at that part of its peripherywhich is farthest toward the rear of the machine and at a distance apartequal to the distance between the 0 and adapted to engage with the slotsP P in the ring F when said block is drawn down.

K is the letter-space-ratchet rocking frame.

The operation of the above-described device is as follows: lVhen thesmall letter is being used, the upper end of the lever II is held backby the spring V. The wire J is held by the slot g in the ring F, throughwhich it passes, in that position which holds the loop j upon the wristfot the crank which operates the type-bar which carries the smallletter. When the key U is struck, a small letter is written. If: theoperator wishes to write a capital letter, he presses upon the key uponthe end of the lever I], thus oscillating said lever about its pivot hand turning the ring F about the bearing of the hub C in the lug T. Bythe movement of said ring the wire J is carried sidewise, carrying theloop j over upon the wrist of the crank which operates the type-barcarrying the capital letter, so that when the key U is struck a capitalletter is written. When the lever II is released, the spring w forces itback, carrying the ring F with it and moving the loop j back onto thewrist of the crank which operates the bar carrying the small letter.Every time a letterkey is struck the arm L is drawn downward, carryingwith it the block 0, thus drawing the tooth 13 into the slot P when acapital letter is written and into the slot P when a small letter iswritten. when the tooth p is in one of the slots P P, the ring F isprevented from turning. Therefore the ring F cannot move except whenboth the type-bars are down and the wrist f is in line with the wrist 6.This description of the operation of the device in respect to thetype-bars I 2' applies to all the other type-bars.

Having fully described my invention, what 0 I claim, and desire tosecure by Letters Patcut, is-

1. The combination, in a type-writing machine, of a pair ofseparately-movable typelevers, one carrying the capital and the otherthe small letter, a key for each pair of type levers, a rod normallyconnecting said key with the type-lever carrying the small letter, arotatable ring connected with all said connecting-rods, and lockingmechanism operating on said ring and connected with all the key-levers,substantially as shown and described.

2. In a type-writing machine, a pair of independently-movable leverspivoted side by side, one carrying a capital letter and another the sameletter in small type, a pivoted key, a connecting-rod pivoted to saidkey and normally engaging with the lever carrying the small character,and means, substantiallysuch as described, for shifting saidconnecting-rod from one type-lever to the other, substantially as shownand described.

3. In a type-writing machine, the combination of pairs ofseparately-movable type-levers, a key for each pair, a rod positivelyconnected with each of said keys and shiftably connected with one of thetype-levers, a slot ted rotatable ring adapted to shift the said rods,and a spring-retracted lever adapted to 70 rotate said ring,substantially as described.
